This invention relatesto minerslamps,

In miners lamps as ordinarily constriurt ed, there is but one-burnerandas a conacetylene gas.

sequence if this burner heeomes clogged or blocked so that a et ofgascannot issue therefrom, the miner is obliged to stop work and clean outtheopening of the burner, thus losing time. lene lamps it isusual toconnect the-body ofthe lainp'to the water reservoir and generatorbymeans of! screw-threads The carbide causes, a sort of cement to.forinbetween these screw-threadsgand as a conse-v quence the lower portion ofthe lamp-f can; i not be unscrewed from the"upperportion and the lampmust {be thrown gawaywor the lower portion of the lamp broken off inattempting tounscrew and detach the water reservoir and generator. theordinary miners" lamps of tl1isrharacter there is a ca clasp which is-mounted: upon the-lamp itself and which forms an.

encumbrance.

One of the objects-pt the present inven.

tion is to provide a lamp oiithischaracter Y with two burners and avalve shit table to close one of the; burners and ,permit the passageofithe gas through the other burner,

or close off the last named burner and per-v mit the passage of the gasthroughthe first issuing from theburner which is open thus named burnerso that ifo-ne of the burners become clogged it is only necessary forthe valve to be shifted and thediminishinp; flame from the cloggedburnerwi ll light the jet permitting the miner toxclean out the cloggedburnerat-his,leisure.

further object is to provide ver y' sim. ple means wherehythis openingand; closing ofthe two' burnersmaybe accomplished. a

still further object is to provide fora detachable connection betweenthe baseor generating portion of the lamp. fandthe bodyof; the lamp'whichydoes not require .erator and the body will be held in to miners lmp "using i a e a I lasp-auditin permi i i b9 handled Furthermore, inminers acety- Furtheurm'ore in I body and generator to bereadilydetached i 1 Be itknown that I, P u'rnn Mrsmo a citifrom 2 each otherwhen necessary, this con nectionbeingsuch, however, that thewgen gastight engagementflw tn each other.

The; body 1.1 has the usur'. formand is I a vertical, sectional view drawings; 10 desig,

closed at its upper end bjy a plate 12 having it iDi-sposed between thecontronting ends ofithe tubes15and 16is atsleeve 18 which encloses asolidrubber block 19 constituting a valve. Whenthissleeve 18 is shiftedin one direction, the-rubberqbloclr will bear against one of the a ends17 and close this particular gastube', while when it is shifted theother direction it will close theother gas tube The amount of thismovement nece'ssaryinorder to obscene or the other eee eea i veras htvhe e v 8 h a laterally projecting portion 20 which isinteriorlyscrew-threaded, and engaging this interior screw-thread is a wire or rod21 which extendsout through a tube 22 which is attached to the wall ofthe body i1 and projects in both directions from this,

wall. Within this tube is disposed a rubber sleeve 23 which fits aroundthe wire or rod 21 tightly so as toprevent the escape of gas, thissleeve forming a packing.

Fitting over the outer projecting end of the tube 22 is a cap 24 whichis longitudinally movable upon the tube 22 and which has an interiorrubber lining or sleeve 25 ting the tube closely. The rod or wire 21 1sattached at its end to this'cap 24 so that when the cap moveslongitudinally the wire or rod will move longitudinally'and vice versa.The extremity of the 'cap'has an in-f ternally screw-threaded socketwith which a screw 26 is adapted to engage, and attached to this cap 24by the screw 26 is an outward ly projecting arm 27, the extremity ofwhich is perforated. Projecting from the sidewall of the body 11 andattached firmly thereto is an interiorly screw-threaded, tubular'member28, and having screw-threaded engagement with this member is the rod 29.The

arm 27 to the cap 25 and thus to the rod 21,

which by reason of its connection to the sleeve 24; causes the valveconstituted b this sleeve and the plug 19 to shift longitudinally intoengagement with one or the other of the branches 17 of the gasfpipes 15or 16. Normally, of course, this valve is held against one of thebranches 17 so as toper- 'mit the free entrance of gas into the otherbranch and its exhaustthrough the appropriate gas pipe or tip. If thistip of the gas pipe becomes clogged so thatthe light is reduced or isfailing, then the handle on the rod.29 is turned and this causesthemovement of the valve 20 in the manner heretofore describedso as toclose this clogged pipe to the entrance of gas and permit the entranceof gas into the unclogged pipe. It will, of course, be understood thatthe branches, 17 of the pipe'16 open beneath the septum,3l which formsthe bottom of the water chamber 32 Extending downward from the waterchamber is the usual water supply pipe 33 which discharges intolthecarbide receptacle l0 and they discharge of water is controlled by theusualvalve, the

valve rod of which is designated34. Inasmuch astlns valve and valve rodare'comseat 37 for agasket '38, against which the flared lower end ofthe bod 11 bears. For the purpose of securely holc ing thebody 11 to thecarbide receptacle and generator 10, 1 form the upper end of the portion10 with an interrupted flange '39, this flange beinginterrupted ata'plurality of points, as at 40. The flange adjacent each interruptionis bevelled, as n41. The body has attached to it a plurality ofdownwardly extending hooks 42 which extend downward and outward'and'then sharply inward, and when the body and generator are puttogether these hooks pass down through the interruptions 40 and then thebody of the lamp is given a turn in one direction and the hooks movealong the bevelled face 41 anddraw the body 11 into close and gas-tightengagement with the carbide receptacle or generator 10. Thisconstruction avoids the necessity of using screw-threads and provides aconstruction whereby the two sections of the lamp may be readilyseparated from each other and readily and quickly joined and avoids theobjections before referred to in I cident to screw-threading the twosections together. v The body portion 11 is provided with the usual hook43 whereby the lamp may be connected to the miners cap. This hookis madesomewhat longer than. the usual hook and extends downward and across thecircumferentialrecess 44 in the body 11. A clip 45 formed of astrip ofresilient metal is intended to'be attached to the miners cap,this stripat its middle being folded or'corrugated, as at 46, to provide aresilient socket 4T betweenth'e corrugations which is adapted to embracethat portion of the hook 43 which extends across'the recess l li Theadvantages of'my invention reside in the fact thatby having two burners,when one burner is blocked the miner can turn it off and turn the otheron and so have a light immediatelyythus losing no time in looking for alight while attempting to drill out the blocked burnerQ The other burnercan be drilled at h'isleisure, WVhen a'burner is blocked, it is seldo'mcompletely blocked so that a little light still shows and thus when theother burner is turned on it lights without the useo'f a match. Thevalve, it will be seen,is madein three pieces so that any one of'thern'can be removed and replaced in case of necessity. The advantage of theclasp 4:5 is that the clasp is always on the'miners cap and does notmake the lamp ungainly and hard tohandl'efas it would do-if theclaspwere on the lamp. At the same time it embraces the hookstrongly andholds the lamp" firmly in place against accidental o detachment orswinging. By disposing the valve between the two branches 17, it isobvious that the valve in shifting from a position closing one gas pipeto a position closing the other gas pipe will traverse a point whereboth pipes are open so that the gas is passing to the clogged *pipe andto the free pipe at the same time so that the gas issuing from the freepipe can become ignited from "the small. amount of clogged pipe.

' IVhile I have illustrated certain details ofconstruction which I havefound to be particularly effective, it is obvious that these detailsmight be changed in many "ways without departing fromthe spirit of theinvention, and it will be-obvious that various attachments ordinarilyfound in miners lamps may be used with a lamp constructed in accordancewith the present invention,

described, a body constituting a water I containing chamber, a pair ofburner pipes chamber and a'carbide chamber connected to the body butseparated from the water extending through the side wall of the body andopening into the carbide chamber, said pipes having confronting innerends, a valve disposed between the confronting ends of the burner pipesand shiftable into contact with one or the other of the burner pipes,and means exterior to the body whereby the valve may be shifted.
